MACHINE FOR GRINDING DISKS OR ..:mi:l

Application filed April 17, 1923. Serial No. 632,730.

To all whom it may concern:

Be it known that I, KARL OsKAR LEON, a subject of the King of Sweden, and residing at London, E11 land, have invented a certain new and useful Improvement in Machines for Grinding Disks or Rollers, of which the following is a specification.

The subject of this invention is a machine for oil grinding disks or rollers for use in disk or roller bearings and has for one of its objects to provide a machine for this purpose in which the grinding of a considerable number of disks or rollers may be completed at one time.

The grinding machine of the invention includes a drum or casing coaxial with a rotary shaft and provided on its inner peripheral surface with one or more ooved rings wholl within the drum or casing, between whic rings and grooved rings carried by arms or the like rotatin with the shaft in the plane or planes 0 the first named ring or rings and also wholly within the drum or casing may be arranged in circular series the disks or sellers to be ground. A secondary feature consists in the provision for axial adjustment of the grooved rings as the disks or rollers being ground diminish in size. Other features will hereinafter appear and will be pointed out in the claims.

The invention is illustrated in the accompanying drawings in which Fig. 1 is a section of one half of the drum or casing of one form of machine provided with two sets of grinding devices. Fig. 2 is a side elevation partly in section and Fig. 3 a front view of the machine. Fig. 4 is a view similar to Fig. 3 but showing the casing swung through 90 on a horizontal axis with an end spider raised to permit insertion of disks or rollers to be ground. Fig. 5 is a detail sectional view of a fragment of Fig. i. Fig. 6 is a fragmentary detail view in section at right angles to Fig. 1 showing part of an abrading ring and an annular resilient support therefor.

As shown, the machine comprises an annular casing 01 supported by spiders b or the like from bushes penetrated by a shaft 0. On the inner peripheral surface of the casing-a are fitted a pair of grooved rings 0? preferably of cast iron between which grooved rings (1 and pairs of rings e, which may be considered as sections of transversely split grooved 1: also preferably of cast iron, are fitted in circular series the disks or rollers g to be ground. Each pair of rings 6 is carried in a peripheral recess h in a double disk 7 formed with a hub f embracing the shaft 0, the halves of each double disk being pressed towards one another by means of springs i coiled around the shaft 0, distance pieces is, Z, m being located on the shaft 0 to form abutments for the springs z. Suitably the minimum distance between the halves f of each double disk and hence the minimum size to which the rollers y can be ground is determined by adjustment of a set screw or set screws 12. extending through one of the halves and forming a stop for the other. On both sides of each grooved ring (1 there are mpped between the ring (2 and abutment ledges on the casing and relative spider resilient rings 0 from which extend rings presenting abrading surfaces 1' for gun ing the flat end faces (as shown at the right hand side of Fig. 1) of the rollers or the surfaces around the central passa es in the rollers where such are provided as shown at the left hand side of Fig. 1). Rollers having such central passages may be positioned by pins 8 extending through said passages.

As shown in Fig. 3, the shaft 0 is coupled to a driving or ulley shaft 2. The casing a is mounte on trunnions t at right angles to the shaft 0 and fitted with a toothed sector it engageable by a pinion 'v rotatable by manual operation whereby the casing a may be swung in either direction through 90, e. g., may be moved into the position shown in Fig. 4, the coupling be tween the shaft 0 and the pulley shaft permitting such movement. To facilitate loading and unloading of the rollers, the spiders b are movable axially on the shaft 0 away from the rings 02, being normally held in place by means of swing bolts to fitted with wing nuts 00 and engaging slots 3 in flanges of the casing and spiders.

To load or unload the rollers, the spider b is raised as best shown in Fig. 5 and the halves of the double disk f relatively moved apart, the rollers being introduM and withdrawn through the gap between the spider and the casing.

The shaft 0 is bored with a central p sage a leading by way of radial a between the halves of the doub e dis to the space between the two e of each pair, whereby emery powder or other grinding medium and oil may be supplied to the rings 0.

In operation, the casing a is brought into Fig. 4 position and a series of rollers inserted between the rings 03 and e, which are in Fig. 5 position. The halves of the double disk 7 are adjusted relatively to one another and the upper spider lowered and clamped. in place. The casing is then inverted and the rollers of the second series are inserted in similar manner.

The casing is now swung into Fig. 3 position and the shaft 0 coupled with the pulley shaft 2.

The shaft 2, which carries fast and loose pulleys, being new rotated, the shaft 0 and therewith the disks 7 and rings 6 are rotated.

The rollers 7 roll on the tracks presented by the rings (Z held stationary by the casing a and are ground between the cooperating rings (1 and e, the abrading rings p efiecting abrasion of the end faces of the rollers.

What I claim is a 1. A machine for grinding disks or rollers comprising a casing, a rotary shaft within said casing, a grooved ring on the inner periphery of the casing wholly within the casing, and a grooved ring carried by the shaft in the plane of the first named ring, one of these rings being split transversely.

means comprising a casing, a rotary shaft within said casing, a grooved ring on the inner periphery of said casing, a grooved ring carried by the shaft in the plane of the first ring, one of said rings being split transversely, and spring means urging towards one another the sections of said split ring.

4. A machine for grinding disks or rollers comprising a casing, a shaft within said casing, a grooved ring on the inner periphery of said casing coaxial with said shaft, a grooved ring in the plane of the first ring and carried by said shaft, one of said rings being split transversely, and means for supplying oil through said shaft to said second named ring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
